什么是重置USB蜂窝调制解调器的AT命令?

什么是用于重置USB蜂窝调制解调器的AT命令序列?

是否可以使用单个AT命令?或者它是否需要几个序列才能重置USB蜂窝调制解调器?

我有华为E272和E220但是如果有任何标准的AT命令,我也对一般命令序列感兴趣.

重置调制解调器是制造商特定的AT命令.

华为AT命令here.有一个在线规范

请看3.10 CFUN部分

The EXECUTION command is used to set the MS mode or restart the MS

AT CFUN有2个参数:

AT+CFUN=[fun[,rst]]

这两个参数有趣,第一个定义如下:

fun:
0 Set as minimum functionality mode (set the RF off but keep
the SIM power on, previous mode must not be offline)
1 Set as online mode (default value) (previous mode must not be offline)
4 Set as offline mode (previous mode must not be FTM)
5 Set as offline FTM (previous mode must be online)
6 Reset MS (previous mode must be offline)
7 Set as RFoff mode (about radio frequency)

rst: Whether to restart MS before setting 0 Not restart MS before setting. (Default) 1 Restart MS before setting. (fun must be 1)
